TECHNICAL FIELD

This disclosure relates generally to crop harvesting, and relates moreparticularly to automated systems for selectively picking crops fromplants.

BACKGROUND

Various crops, such as strawberries, have been harvested typically usingmanual labor due to the delicate nature of the crops and the selectivenature of the harvesting. For example, laborers perform the harvestingby selectively picking ripe crops from the plants while leaving unripecrops on the plants for later harvesting when they have ripened. Thehigh seasonal demand for laborers and the limited labor force hasresulted in increased labor costs and crops being left unpicked.Further, labor shortages have resulted in portions of fields being leftunplanted in order to avoid the effort, expense, and waste involved withgrowing unpicked crops.

In many embodiments, first strip 414and/or second strip 424 can be made of a flexible and/orabrasive-resistant semi-rigid material, such asultra-high-molecular-weight (UHMW) polyethylene (UHMWPE). As shown inFIGS. 4-5, as displacement block 430 is adjusted radially outward onspoke 317, first strip 414 can push first claw piece 410 forward torotate around hinge 419 to the closed position, and first linkage piece415 can slide outwardly along first strip 414 away from displacementblock 430 as the position of first displacement mounting portion 416 isadjusted. Similarly, as displacement block 430 is adjusted radiallyoutward on spoke 317, second strip 424 can push second claw piece 420forward to rotate around hinge 429 to the closed position, and secondlinkage piece 425 can slide outwardly along second strip 424 away fromdisplacement block 430 as the position of second displacement mountingportion 426 is adjusted.

In several embodiments, as displacement block 430 is adjusted radiallyoutward on spoke 317, first strip 414 and/or second strip 424 can bendbackward (i.e., toward a center of frame 316 (FIG. 3)) to account forfirst claw piece 410 and/or second claw piece 420, respectively, notfully pushing forward in their rotation around hinge 419 and/or hinge429, respectively. For example, if gripper 312 is utilized to pick alarge-size crop, the size of the crop can prevent first claw piece 410and/or second claw piece 420 from being fully pushed forward in theirrotation around hinge 419 and/or hinge 429, respectively. Whendisplacement block 430 is adjusted radially outward on spoke 317, firststrip 414 and/or second strip 424 can provide spring-loaded bias onfirst claw piece 410 and/or second claw piece 420, respectively, tosecurely hold a crop (e.g., strawberry 535) in gripper 312. In a numberof embodiments, the spring-loaded bending of first strip 414 and/orsecond strip 424 can advantageously allow gripper 312 to pick crops ofvarious different sizes and securely hold those different-sized cropswithout damaging the crops. For example, gripper 312 can be configuredto pick strawberries ranging from small-sized strawberries tolarge-sized strawberries.

In many embodiments, bearing1012 can be centered on displacement pin 1032, and can rotate along therotational path of stationary cam 669. Similarly, gripper 313 caninclude a displacement pin 1033 and/or a bearing 1013; gripper 314 caninclude a displacement pin 1034 and/or a bearing 1014; and/or gripper315 can include a displacement pin 1035 and/or a bearing 1015.Displacement pin 1033, displacement pin 1034, and/or displacement pin1035 can be similar or identical to displacement pin 1032. Bearing 1013,bearing 1014, and/or bearing 1015 can be similar or identical to bearing1012.

In many embodiments, motor 654 (FIGS. 6-8) can rotate picking apparatus110 in a counter-clockwise direction, as viewed from the rearperspective shown in FIGS. 10-11. Gripper 312 can be rotated to pickingposition 966 of second portion 965 of the rotational path of thegrippers (e.g., 312-315 (FIG. 3)) along stationary cam 669. In manyembodiments, stationary cam 669 can include a stopping edge 1066, whichcan stop bearing 1012 in the rotation of picking apparatus 110 to stopgripper 312 at picking position 966. In many embodiments, when gripper312 is in picking position 966, gripper 312 can be facing downward toallow gripper 312 to pick a crop from a growing bed. When gripper 312 isrotated to picking position 966, actuation cam 660 can be rotated suchthat cam interface piece 960 of actuator 661 can be at base point 962 ofactuation cam 660 and actuator 661 is adjusted upwards (e.g., retracted)with respect to stationary cam 669. When actuator 661 is in theretracted position, as shown in FIG. 10, gripper interface portion 969of actuator 661 can be at or proximate to second portion 965 ofstationary cam 669, such that gripper 312 can remain in the openposition.

In several embodiments, as gripper 312 rotates toward picking position966, gripper 315 can rotate along the rotational path of stationary cam669 from first portion 964 to second portion 965 at release position967. In many embodiments, stationary cam 669 can include a release edge1067, which can allow gripper 315 to gradually open from the closedposition (as shown in FIG. 5) to the open position (as shown in FIG. 4)at release position 967. When gripper 315 is rotated to release position967 and opens to the open position, gripper 315 can release a crop thatit is holding, such as in a collection device. When gripper 312 is atpicking position 966 and gripper 315 is at release position 967,grippers 313 and 314 can be positioned along first portion 964 of therotational path of stationary cam 669, which can hold grippers 313 and314 in the closed position, as shown in FIG. 10. For example, grippers313 and 314 can each be holding a crop.

In many embodiments, at picking position 966 and in the open position,as shown in FIG. 10, gripper 312 can be ready to pick a crop from aplant. In several embodiments, carrier 170 (FIG. 1) can move carriagesupport assembly 140 such that gripper 312 is positioned over the cropto be picked. Motor 653 (FIGS. 6-8) can rotate actuation cam 660 toengage gripper interface portion 969 of actuator 661 with displacementpin 1032 of gripper 312 to adjust the position of first claw piece 410(FIGS. 4-5) and second claw piece 420 (FIGS. 4-5) of gripper 312 inorder to fit around the individual crop to be picked. For example, ifthe crop is a larger, such as a large-sized strawberry, gripper 312 canbe set to a wider opening in the open position, and if the crop issmaller, such as a small-sized strawberry, gripper 312 can be set to anarrow opening in the open position, which can allow gripper 312 toseparate and/or isolate the individual crop to be picked from the othernearby crops without damaging the nearby crops.

When gripper 312 is adjusted to the appropriate opening width for thecrop to be picked, carriage support assembly 140 can lower carriage 150such that first claw piece 410 (FIGS. 4-5) and second claw piece 420(FIGS. 4-5) of gripper 312 can surround the crop to be picked. Motor 653(FIGS. 6-8) can rotate actuation cam 660 such that cam interface piece960 can move along actuation cam 660 to peak point 963, which can pushextend actuator 661 to an extended position, as shown in FIG. 11. Asactuator 661 is extended, gripper interface portion 969 of actuator 661can push displacement pin 1032 to adjust the position of gripper 312 tothe closed position (as shown in FIG. 11). When gripper 312 is in theclosed position, bearing 1012 of gripper 312 can be extended beyondstopping edge 1066 of stationary cam 669, such that gripper 312 can berotated along first portion 964 of the rotational path of stationary cam669. In many embodiments, gripper 312 can securely hold the picked cropas gripper 312 rotates along first portion 964. After gripper 312 picksthe crop, motor 654 (FIGS. 6-8) can rotate picking apparatus 110 suchthat gripper 315 is rotated to picking position 966. Although pickingapparatus 110 is shown with 4 grippers (e.g., 312-315), pickingapparatus 110 can include fewer or additional grippers, and firstportion 964 and second portion 965 of the rotational path of stationarycam 669 can be adjusted accordingly.

FIG. 24 illustrates a right side view of carriage assembly2040, picking apparatus 2010, collection apparatus 2001, and cropejector 2004, in which picking apparatus 2010 is in a raised positionand gripper 2015 in the offload position is in a closed position. FIG.25 illustrates a rear side view of carriage assembly 2040, pickingapparatus 2010, collection apparatus 2001, and crop ejector 2004, inwhich picking apparatus 2010 is in the raised position and gripper 2015in the offload position is in the closed position. FIG. 26 illustrates aright side view of carriage assembly 2040, picking apparatus 2010,collection apparatus 2001, and crop ejector 2004, in which pickingapparatus 2010 is in the raised position and gripper 2015 in the offloadposition is in the open position. FIG. 27 illustrates a rear side viewof carriage assembly 2040, picking apparatus 2010, collection apparatus2001, and crop ejector 2004, in which picking apparatus 2010 is in theraised position and gripper 2015 in the offload position is in the openposition.

In many embodiments, the grippers (e.g., 2011-2015, 2116) of pickingapparatus 2010 can be spring biased in a closed configuration. Forexample, gripper 312 shown in FIG. 4, can be modified such thatcompression spring 432 (FIG. 4) can be situated on the other side of pin431 to bias displacement block 430 outward along spoke 317 to adjustgripper 312 to the closed position, such as the closed position ofgripper 312 in FIG. 5. In yet another embodiment, compression spring 432can be situated in the same position shown in FIG. 4, but can bereplaced with an extension spring, which can similarly bias displacementblock 430 outward along spoke 317 to adjust gripper 312 to the closedposition. In many embodiments, each of the grippers (e.g., 2011-2015,2116) of picking apparatus 2010 can include a claw cushion, such as clawcushion 2317 shown on gripper 2012 in FIG. 23, or claw cushion 2718shown on gripper 2015 in FIG. 27. In many embodiments, the claw cushion(e.g., 2317 (FIG. 23), 2718 (FIG. 27)) can provide a surface on theinside of the gripper (e.g., 2011-2015, 2116) to prevent a picked cropin the gripper (e.g., 2011-2015, 2116) from being displaced from betweenthe claw pieces (e.g., 410, 420 (FIG. 4)) and falling into a hingeregion proximate to the hinges (e.g., 419, 429 (FIG. 4)). For example,when gripper 2015 opens in the offload position in FIG. 27, crop cushion2718 can prevent a crop within gripper 2015 from falling into the hingesof gripper 2015.

In many embodiments, picking apparatus 2010 can move the grippers (e.g.,2011-2015, 2116) in a rotational path centered with respect to thecentral axis of picking apparatus 2010. In several embodiments, apicking position can be located at the bottom of the rotational path,such as the position of gripper 2012 shown in FIGS. 22-27. In otherembodiments, the picking position can be located at a different locationof the rotational path, such as a side of the rotational path, or a topof the rotational path. In many embodiments, each of the grippers (e.g.,2011-2015, 2116) can be configured to be opened to an open position,such as the open position of gripper 312 in FIG. 4, when the gripper(e.g., 2012) is located at the picking position, as shown in FIGS.22-23. In many embodiments, the gripper (e.g., 2012) located at thepicking position can be opened to the open position to pick a crop.

In several embodiments, the gripper (e.g., 2012) located at the pickingposition can be opened to the open position before or while pickingapparatus 2010 and the gripper (e.g., 2012) in the picking position islowered to pick the crop. In many embodiments, the gripper (e.g., 2012)in the picking position can be opened using an actuator, such asactuator 2210. In many embodiments, actuator 2210 can be configured toengage with a pin of the gripper, such as pin 431 in FIG. 4 ordisplacement pin 1032 in FIG. 10, described above, and move the pin toadjust the position of the claw pieces (e.g., 410, 420 (FIG. 4)) of thegripper (e.g., 2012) and adjust the gripper (e.g., 2012) to the openposition. In many embodiments, actuator 2210 can pull the pin inwardalong the spoke (e.g., pulling pin 413 inward along spoke 317 in FIG. 4)to open the gripper (e.g., 2012). In many embodiments, actuator 2210 canbe configured to adjust the position of the claw pieces (e.g., 410, 420in FIG. 4) in order to fit around the individual crop to be picked, assuch described above in connection with actuator 661 in FIG. 10.

In a number of embodiments, before picking apparatus 2010 and thegripper (e.g., 2012) in the picking position is lowered to pick thecrop, and after picking apparatus 2010 and the gripper (e.g., 2012) inthe picking position is raised (e.g., with the crop in the gripper(e.g., 2012)), picking apparatus 2010 and the gripper (e.g., 2012) inthe picking position can be positioned in the raised position, as shownin FIGS. 24-25. In many embodiments, when picking apparatus 2010 is inthe raised position, each of the grippers (e.g., 2011-2015, 2116) can bein the closed position, which can allow picking apparatus 2010 to berotated with one or more crops in one or more of the grippers (e.g.,2011-2015, 2116).

In many embodiments, when picking apparatus 2010 is in the raisedposition, one of the grippers (e.g., gripper 2015) can be opened to theopen position to offload a crop from the gripper (e.g., 2015), such asshown in FIGS. 26-27. In a number of embodiments, an offload positioncan be located at the top of the rotational path, such as the positionof gripper 2015 shown in FIGS. 22-27. In other embodiments, the offloadposition can be located at a different location of the rotational path,such as a side of the rotational path, or a bottom of the rotationalpath. In many embodiments, each of the grippers (e.g., 2011-2015, 2116)can be configured to be opened to an open position, such as the openposition of gripper 312 in FIG. 4, when the gripper (e.g., 2015) islocated at the offload position, as shown in FIGS. 26-27. In manyembodiments, the gripper (e.g., 2015) located at the offload position beopened to the open position to offload a crop from the gripper (e.g.,2015).

In many embodiments, the gripper (e.g., 2015) in the offload positioncan be opened using an actuator, such as actuator 2220. In manyembodiments, actuator 2220 can be configured to engage with a pin of thegripper, such as pin 431 in FIG. 4 or displacement pin 1032 in FIG. 10,described above, and move the pin to adjust the position of the clawpieces (e.g., 410, 420 (FIG. 4)) of the gripper (e.g., 2015) and adjustthe gripper (e.g., 2015) to the open position. In many embodiments,actuator 2220 can pull the pin inward along the spoke (e.g., pulling pin413 inward along spoke 317 in FIG. 4) to open the gripper (e.g., 2015).

In a number of embodiments, once the gripper (e.g., 2015) in the offloadposition is open, crop ejector 2004 can eject the crop in the openedgripper (e.g., 2015) in the offload position into collection apparatus2001. For example, actuator 2006 can move ejection plate 2005 towardcollection plate 2001, as shown in FIG. 26. In many embodiments,ejection plate 2005 can be configured to fit between the claw pieces(e.g., 410, 420 (FIG. 4)) of the gripper (e.g., 2015) in the offloadposition when the gripper (e.g., 2015) is in the open position.

In several embodiments, each of the grippers (e.g., 2011-2015, 2116) canpick a different individual crop, and picking apparatus 2010 can beconfigured to offload (e.g., continuously offload) the crops whilepicking apparatus 2010 is picking the crops in the individual grippers(e.g., 2011-2015, 2116). For example, crops can be offloaded during atime in which crops are being picked. In some embodiments, a gripper(e.g., 2011-2015, 2116) can pick a first crop at a first time. Later, agripper different from the gripper that picked the first crop can pick asecond crop, after which a gripper different from the gripper thatpicked the second crop can pick a third crop. During the time betweenthe second crop and the third crop being picked, the first crop can beoffloaded from the gripper that picked the first crop. In someembodiments, the gripper that picked the first crop can pick the thirdcrop. In other embodiments, the gripper that picks the third crop can bedifferent than the gripper that picked the first crop. In manyembodiments, the second crops can be held in the gripper that picked thesecond crop when the first crop is offloaded from the gripper thatpicked the second crop. In a number of embodiments, the second crop andthe third crop can be held the grippers that picked them respectivelywhen the third crop has been picked.

In many embodiments, using picking apparatus 2010, as shown in FIGS.20-27, gripper 2012 in the picking position can pick a crop and gripper2015 in the offload position can offload a crop from gripper 2015.Picking apparatus 2010 can rotate such that gripper 2013 (of if rotatedthe other rotational direction, gripper 2011) can pick a crop whilegripper 2012 holds the crop until it is rotated to the offload position.Picking apparatus 2010, in the embodiment shown in FIGS. 20-27, can holdup to four individual crops at a time when gripper 2012 has just pickeda crop and gripper 2015 has not offloaded the crop, as gripper 2013 andgripper 2014 can also be holding crops. Gripper 2116 and gripper 2011can be empty. In other embodiments, a crop in the gripper (e.g., 2015)in the offload position can be offloaded before the gripper (e.g., 2012)in the picking position is used to pick a crop, in which case pickingapparatus can hold up to three crops. In several embodiments, a seriesof picks and offloads can be interleaved, with a pick followed by anoffload, followed by a pick, followed by an offload, etc. In severalembodiments, during this entire series of picks and offloads, pickingapparatus can be holding at least one crop. In other embodiments,picking apparatus can be holding at least two crop, three crops, fourcrops, or another suitable number of crops each in individual grippers.In still other embodiments, a crop in the gripper (e.g., 2015) in theoffload position can be offloaded simultaneously with the gripper (e.g.,2012) in the picking position picking a crop. In such embodiments, thegripper can be considered to have offloaded the first crop during thetime period between the second crop and the third crop being picked, asdescribed above. In yet other embodiments, picking apparatus 2010 caninclude a different number of grippers, as described above. For example,picking apparatus can include two grippers, and a pick in one of the twogrippers can be followed by an offload in the other gripper, after whichthe other gripper can pick another individual crop.

In many embodiments, the continuous offload of crops from the grippers(e.g., 2011-2015, 2116) of picking apparatus 2010 can beneficially allowharvesting robot 2000 to pick many crops while rotating around a plant.For example, if a plant has seven ripe crops that are ready to bepicked, harvesting robot 2000 can circle the plant, and pick the sevenplants while simultaneously offload at least some of the crops whilecircling the plant and picking the seven crops. The offloaded crops canadvantageously be collected in collection apparatus 2001.

The leaf displacement systemcan be employed in many different embodiments or examples notspecifically depicted or described herein. Leaf displacement system 2800can be similar to foliage displacement mechanism 1400 (FIG. 14), andleaf displacement system can be configured to move foliage of a plant,such as foliage 1512 of plant 1510, to expose at least a portion of thecrops under the foliage, which can allow imaging sensors 1290-1291(FIGS. 12-13) and/or images sensors 2190-2191 (FIG. 21) to detect thecrops and/or allow the grippers (e.g., 312-315 (FIGS. 3, 10-11),2011-2015 (FIGS. 20-21), 2116 (FIG. 21)) to pick the crops, such ascrops 1511.

In a number of embodiments, leaf displacement system 2800 can include asupport structure 2810, a first assembly 2850, and/or a second assembly2870. In many embodiments, first assembly 2850 and second assembly 2870can each be movably coupled to support structure 2810, as shown in FIGS.28-31. In other embodiments, one of first assembly 2850 and secondassembly 2870 can be movably coupled to support structure 2810 and theother one of first assembly 2850 and second assembly 2870 can be fixedlycoupled to support structure 2810. For example, leaf displacement system2800 can include a first assembly rail 2815 to movably couple firstassembly 2850 to support structure 2810 and allow first assembly 2850 toextend from and/or retract to support structure 2810. Leaf displacementsystem 2800 can include a second assembly rail 2817 to movably couplesecond assembly 2870 to support structure 2810 and allow second assembly2870 to extend from and/or retract to support structure 2810. In severalembodiments, support structure 2810 can include one or more motors (notshown) to drive the extension/retraction of first assembly 2850 alongsecond assembly rail 2815 and/or the extension/retraction of secondassembly 2870 along second assembly rail 2817.

In some embodiments, leaf displacement system 2800 can include two ormore surfaces, which can be movable with respect to each other, and canpush and/or hold foliage 1512 toward center 1513 of plant 1510. In someembodiments, for example, each of the two or more surfaces can be curvedor flat surfaces, which can push foliage 1512 toward center 1513. Asshown in FIG. 28, second assembly 2870 can include a second assemblybase surface 2871, a second assembly first wing surface 2872, and asecond assembly second wing surface 2873.

In many embodiments, second assembly base surface 2871 can be fixedlycoupled to second assembly rail 2817, and second assembly first wingsurface 2872 and second assembly second wing surface 2873 can eachrotate with respect to second assembly base surface 2871. For example,in some embodiments, leaf displacement system 2800 can include arms2821-2822 and gear 2831, with arm 2821 coupled to gear 2831 at one endof arm 2821 and coupled to arm 2822 at the other end of arm 2821, andarm 2822 coupled to arm 2821 at one end of arm 2822 and coupled tosecond assembly first wing surface 2872 at the other end of arm 2822,such that when gear 2831 rotates, second assembly first wing surface2872 can be rotated. Similarly, leaf displacement system 2800 caninclude arms 2823-2824 and another gear (not shown), with arm 2823coupled to the gear at one end of arm 2823 and coupled to arm 2824 atthe other end of arm 2823, and arm 2824 coupled to arm 2823 at one endof arm 2824 and coupled to second assembly second wing surface 2873 atthe other end of arm 2824, such that when the gear rotates, secondassembly second wing surface 2873 can be rotated.

In some embodiments, leaf displacement system 2800 can rotate secondassembly first wing surface 2872 and second assembly second wing surface2873 when second assembly 2870 is extended and/or retracted along secondassembly rail 2817. In many embodiments, as second assembly 2870 isretracted along second assembly rail 2817, second assembly base surface2871, second assembly first wing surface 2872, and/or second assemblysecond wing surface 2873 can push foliage 1512 toward center 1513 ofplant 1510.

As shown in FIG. 28, first assembly 2850 can include a first assemblybase surface 2851, a first assembly first wing surface 2852, and a firstassembly second wing surface 2853. In many embodiments, first assemblybase surface 2851 can be fixedly coupled to first assembly rail 2815,and first assembly first wing surface 2852 and first assembly secondwing surface 2853 can each rotate with respect to first assembly basesurface 2851. For example, in some embodiments, leaf displacement system2800 can include arms 2851-2826 and gear 2832, with arm 2825 coupled togear 2833 at one end of arm 2825 and coupled to arm 2826 at the otherend of arm 2825, and arm 2826 coupled to arm 2825 at one end of arm 2826and coupled to first assembly first wing surface 2852 at the other endof arm 2826, such that when gear 2833 rotates, first assembly first wingsurface 2852 can be rotated. Similarly, leaf displacement system 2800can include a first arm (not shown), an arm 2828 and another gear (notshown), with the first arm coupled to the gear at one end of the firstarm and coupled to arm 2828 at the other end of the first arm, and arm2828 coupled to the first arm at one end of arm 2828 and coupled tofirst assembly second wing surface 2853 at the other end of arm 2828,such that when the gear rotates, first assembly second wing surface 2853can be rotated.

In some embodiments, leaf displacement system 2800 can rotate firstassembly first wing surface 2852 and first assembly second wing surface2853 when first assembly 2850 is extended and/or retracted along firstassembly rail 2815. In a number of embodiments, second assembly 2850 caninclude a first assembly first plate surface 2854 and/or a firstassembly second plate surface 2855. In many embodiments, first assemblyfirst plate surface 2854 can be fixedly coupled to first assembly firstwing surface 2852, such that first assembly first plate surface 2854 canrotate when first assembly first wing surface 2852 is rotated. Invarious embodiments, first assembly second plate surface 2855 can befixedly coupled to first assembly second wing surface 2853, such thatfirst assembly second plate surface 2855 can rotate when first assemblysecond wing surface 2853 is rotated.

In many embodiments, as first assembly 2850 is retracted along firstassembly rail 2815, first assembly base surface 2851, first assemblyfirst plate surface 2854, and/or first assembly second plate surface2855 can push foliage 1512 toward center 1513 of plant 1510. In manyembodiments, first assembly base surface 2851, first assembly first wingsurface 2852, first assembly second wing surface 2853, second assemblybase surface 2871, second assembly first wing surface 2872, and secondassembly second wing surface 2873 can each be rounded surfaces, such asa portion of a cylinder. In many embodiments, when leaf displacementsystem 2800 is in the closed configuration, as shown in FIG. 28, firstassembly base surface 2851, first assembly first wing surface 2852,first assembly second wing surface 2853, second assembly base surface2871, second assembly first wing surface 2872, and second assemblysecond wing surface 2873 can form a cylindrical shell that enclosesfirst assembly first plate surface 2854, first assembly second platesurface 2855, and/or foliage 1512.

In several embodiments, second assembly first wing surface 2872 andsecond assembly second wing surface 2873 can each be larger than firstassembly first wing surface 2852 and first assembly second wing surface2853, to allow second assembly first wing surface 2872 and secondassembly second wing surface 2873 to capture more of foliage 1512, asshown in FIG. 29. Because first assembly first wing surface 2852 andfirst assembly second wing surface 2853 are smaller, and unable tocapture as much of foliage 1512, first assembly first plate surface 2874and first assembly second plate surface 2855 can be used by firstassembly 2850 to capture more of foliage 1512, as shown in FIG. 29. Inmany embodiments, first assembly first plate surface 2874 and firstassembly second plate surface 2855 can capture foliage 1512 and sweepfoliage 1512 within the cylindrical shell shown in FIG. 31. As partiallyshown in FIG. 30 by first assembly first plate surface 2854, as firstassembly first plate surface 2854 and first assembly second platesurface 2855 are rotated inward as leaf displacement system 2800transitions from the open configuration (as shown in FIG. 28) to theclosed configuration (as shown in FIG. 31), first assembly first platesurface 2854 and first assembly second plate surface 2855 can sweepwithin second assembly first wing surface 2872 and second assemblysecond wing surface 2873, such that when leaf displacement system 2800is in the closed configuration, as shown in FIG. 30, first assemblyfirst plate surface 2854 and first assembly second plate surface 2855can be fully enclosed within the cylindrical shell described above.

In many embodiments, foliage 1512 can be held within a circumference toexpose crops 1511, and allow a harvesting robot (e.g., 100 (FIG. 1),2000 (FIG. 20)) to rotate around plant 1510 and detect and pick crops1511 without interference from foliage 1512. In many embodiments, thecircumference can be dictated by the type of plant being harvested. Forexample, in some plants, such as strawberry plants, the circumferencecan be no more than approximately 8 inches (20.32 centimeters (cm)), 7inches (17.78 cm), 6 inches (15.24 cm), 5 inches (12.7 cm), or anothersuitable circumference. For other plants, the circumference can beanother suitable circumference.

In many embodiments, foliage displacement system 2800 can be carriedsuch that a bottommost of foliage displacement system 2800, such as abottommost part of first assembly base surface 2851, first assemblyfirst wing surface 2852, first assembly second wing surface 2853, firstassembly first plate surface 2874, first assembly second plate surface2855, second assembly base surface 2871, second assembly first wingsurface 2872, and/or second assembly second wing surface 2873 can be afirst distance from growing bed 1501 when leaf displacement system 2800transitions from the open configuration (shown in FIG. 28) to the closedconfiguration (shown in FIG. 31). In many embodiments, the distance canbe dependent on the size of the crops (e.g., 1511) and/or the typicalsize of the foliage (e.g., 1512) when the crops are being harvested,such that the crops (e.g., 1511) are not captured by leaf displacementsystem 2800, but the foliage (e.g., 1512) is captured. For example, insome embodiments, such as when the crops are strawberries, the distancecan be approximately 2 inches (5.08 cm) to 4 inches (10.16 cm). In otherembodiments, the distance can be approximately 2.5 inches (6.35 cm) orapproximately 3.0 inches (7.62 cm). In other embodiments, the distancecan be another suitable distance.

In many embodiments, leaf displacement system 2800 can be held belowcarrier assembly 2070 (FIGS. 20-21) of harvesting robot 2000 (FIG. 20)or carrier assembly 170 (FIG. 1) of harvesting robot 100 (FIG. 1). Forexample, leaf displacement system 2800 can be held between mountingbearing 2074 (FIG. 20) and plant 1510 when mounting bearing 2074 iscentered over plant 1510. In many embodiments, can be held stationarysuch that leaf displacement system 2800 does not rotate with respect toplant 1510 when harvesting robot 2000 (FIG. 20) or harvesting robot 100(FIG. 1) rotates around plant 1510 to detect and pick crops, which canbeneficially hold foliage 1512 in place without leaf displacement system2800 damaging foliage 1512 or getting caught on foliage 1512.

In many embodiments, when the harvesting robot (e.g., 100 (FIG. 1), 2000(FIG. 20)) corresponding to leaf displacement system 2800 approachesplant 1510, such as a plant along a row of plants, leaf displacementsystem 2800 can be in the open configuration, as shown in FIG. 28,and/or first assembly 2850 can be disposed on one side of plant 1510 andsecond assembly 2870 can be disposed on the opposite side of plant 1510,as shown in FIG. 28, which can beneficially allow the harvesting robot(e.g., 100 (FIG. 1), 2000 (FIG. 20)) and support structure 2810 of leafdisplacement system 2800 to approach plant 1510 and become centered overplant 1510, after which leaf displacement system can transition from theopen configuration to the closed configuration. After the harvestingrobot (e.g., 100 (FIG. 1), 2000 (FIG. 20)) has finished rotating aroundplant 1510 (and finished detecting and picking crops on plant 1510),leaf detection system 2800 can transition from the closed configuration(as shown in FIG. 31) to the open configuration (as shown in FIG. 28).

In other embodiments, a leaf displacement system can have otherconfigurations. For example, a base surface can be surrounded by twowing surfaces, which can each rotate with respect to the base surfaceand can capture foliage 1512 within the base surface the two wingsurfaces, to close in a triangular shape and hold foliage 1512.

FIG. 33 illustrates a rear view of harvestingvehicle 3200 traveling through rows of plant beds 3280. FIG. 34illustrates a top view of harvesting vehicle 3200 traveling through rowsof plant beds 3280. Harvesting vehicle 3200 is merely exemplary, andembodiments of the harvesting vehicle are not limited to embodimentspresented herein. The harvesting vehicle can be employed in manydifferent embodiments or examples not specifically depicted or describedherein.

The rows of plant beds can include plant beds 3281-3290 which can bespaced apart to form rows 3291-3299. Plant beds 3281-3290 can includerows of plants, such as plants 3220. In some embodiments, plant beds3280-3290 can be slightly angled, such as on each side of each of plantbeds 3280-3290 to assist with water run-off. In many embodiments, eachangled side of the bed can include rows of plants. Plants 3220 can be astrawberry plant, a tomato plant, a pepper (e.g., bell peppers, chilipeppers, etc.) plant, an orange tree, or another suitable plant.

In many embodiments, harvesting vehicle 3200 can be used to harvestplants 3220. In many embodiments, harvesting vehicle 3200 can includewheels, such as wheels 3201-3204 and a body 3210. In many embodiments,the wheels can rolls along rows (e.g., 3291-3299) between the plant beds(e.g., 3281-3290). For example, in some embodiments, wheels 3201-3202can roll along row 3292 and wheels 3203-3204 can roll along row 3298,such that harvesting vehicle 3200 straddles six plant beds (e.g., plantbeds 3283-3288), and can be used to harvest four plant beds (e.g., plantbeds 3284-3287) at a time. In other embodiments, harvesting vehicle 3200can straddle more or fewer plant beds and can harvest more or fewerplant beds at a time. In the embodiment illustrated in FIG. 32, rows3291-3299 can be straight, but in a different embodiment, the rows canbe curved.

In many embodiments, body 3210 can include frame pieces 3211-3212, whichin some embodiments can be I-beams or other suitable frame pieces toprovide support for body 3210 across the plant beds (e.g., 3283-3288)straddled by body 3210. In several embodiments, body 3210 can includearms 3213 and 3214 on each side of harvesting vehicle 3200, which caninclude global positioning system (GPS) receivers 3215 and 3216,respectively.

In a number of embodiments, body 3210 can include robot positioningcarrier (RPC) tracks 3334-3337 (FIGS. 33-34). In many embodiments, RPCtracks 3334-3337 can carry robot positioning carriers (RPCs) 3240, 3250,3260, and 3270, respectively. In many embodiments, each RPC can carryrobots, such as harvesting robots 3461-3464 (FIG. 34), as explained ingreater detail below. In several embodiments, body 3210 can include anRPC drive system 3230, which can control the position of RPCs 3240,3250, 3260, and 3270 with respect to RPC tracks 3334-3337.

In many embodiments, RPC drive system 3230 can include an RPC motor3231, an RPC drive block 3232, an RPC drive shaft 3233, and an RPC frame3234. In a number of embodiments, RPC drive frame 3234 can be mounted tobody 3210, such as to frame pieces 3211-3212. In several embodiments,RPC motor 3231 can be mounted to RPC drive frame 3234, and can drive RPCdrive block 3232 to rotate RPC shaft 3233. In many embodiments, RPCshaft 3233 can extend through each of RPC tracks 3334-3337 to controlthe position of RPCs 324, 3250, 3260, and 3270 with respect to RPCtracks 3334-3337, as explained below in greater detail.

Turning ahead in the drawings, FIG. 35 illustrates a top, rear, rightside perspective view of RPC 3260. FIG. 36 illustrates a bottom, front,right side view of RPC 3260 being carried by RPC track 3336 and showinga portion of RPC drive system 3230. FIG. 37 illustrates a rear view of aportion of RPC 3260 being carried by RPC track 3336 and showing a drivemechanism of RPC 3260 using RPC drive shaft 3233. RPC 3260 is merelyexemplary, and embodiments of the RPC are not limited to embodimentspresented herein. The RPC can be employed in many different embodimentsor examples not specifically depicted or described herein. RPC drivesystem 3230 is merely exemplary, and embodiments of the RPC drive systemare not limited to embodiments presented herein. The RPC drive systemcan be employed in many different embodiments or examples notspecifically depicted or described herein.

In many embodiments, each RPC (e.g., 3240, 3250, 3260, 3270) can be thesame as each other, such as RPC 3260. In many embodiments, RPC 3260 cancarry harvesting robots 3461-3464, which can be similar or identical toharvesting robot 100 (FIG. 1) and/or harvesting robot 2000 (FIG. 20). Insome embodiments, each harvesting robot (e.g., 3461-3464) can be includea mounting bearing, such as mounting bearings 3521-3524, respectively.Mounting bearings 3521-3524 can be similar or identical to mountingbearings 1274 (FIG. 12) and/or 2074 (FIG. 20). In many embodiments, RPC3260 can include a carrier frame 3510, which can include mounting pieces3511-3514, which can attached to mounting bearings 3521-3524,respectively. In many embodiments, mounting pieces 3511-3514 can bemodular attachment pieces, which can be removably coupled to harvestingrobots 3461-3464, respectively, such as to quickly replace a harvestingrobot (e.g., 3461-3464) in case of malfunction, or to attach differenttypes of robots, such as hole punching robots, as described below infurther detail.

In several embodiments, RPC 3260 can carry four robots, as shown inFIGS. 35-36. In other embodiments, RPC 3260 can carry another number ofrobots, such as 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12, or another suitablenumber of robots. By carrying multiple robots, RPC 3260 can positionmultiple robots in place to each simultaneously perform tasks, such asharvesting plants or other suitable tasks. In many embodiments, RPC 3260can position the robots such that the robots can perform the taskssimultaneously and independently without interfering with the otherrobots. For example, as shown in FIGS. 35-36, RPC 3260 can space therobots two on each side, with interleaved spacing, as further shown inFIG. 39 and described below.

In many embodiments, for ease of service, each robot (e.g., 3461-3464)can have its own self-contained controller and processors, which canhave communications and/or power connections to the rest of theharvesting vehicle (e.g., 3200 (FIGS. 32-34)). Each one of these robotscan include motor controls, position sensors, solenoid controls,cameras, vision processing, strobe controls, and/or other suitablecomponents. The robots (e.g., 3461-3464) can act like a hive of beesthat are orientated to perform certain tasks or functions when cued andreport back when completed so that the higher-level system in theharvesting vehicle (e.g., 3200 (FIGS. 32-34)) can perform next steps. Inmany embodiments, the robots (e.g., 3461-3464) can perform these basicfunctions simultaneously and independently when commanded. In case ofthe malfunction of one of the robots (e.g., 3461-3464), it isadvantageous to be able to trade out the robot (e.g., 3461-3464) quicklyso that the rest of the robots (e.g., 3461-3464) can continue working. Aquick change-out system for the robots (e.g., 3461-3464) can beimplemented by minimizing the electrical and mechanical connections ittakes to replace a robot (e.g., 3461-3464). By including multiple RPCs(e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34)) each with multiple robots(e.g., 3461-3464) on harvesting vehicle 3200 (FIGS. 32-34), harvestingvehicle 3200 (FIGS. 32-34) can perform operations (e.g., picking, holepunching) on multiple rows during picking operations, increasing pickingefficiency of harvesting vehicle 3200 (FIGS. 32-34). For example,harvesting vehicle 3200 (FIGS. 32-34) show in FIGS. 32-34 includes 16different harvesting robots, which can pick crops on 16 different plantssimultaneously. In other embodiments, harvesting vehicle 3200 (FIGS.32-34) can include more or fewer harvesting robots and/or robots of adifferent type (e.g., hole punching robots or other suitable robots).

In many embodiments, carrier frame 3510 of RPC 3260 can include trackcoupling mechanisms 3515 and 3516, which can be configured to slidablycouple to RPC track 3336. For example, track coupling mechanisms3515-3516 can each include a number of wheels to couple RPC 3260 to RPCtrack 3336 and facilitate movement of RPC 3260 with respect to RPC track3336, as shown in FIG. 36.

In many embodiments, RPC drive shaft 3230 can extend through each RPCtrack, such as RPC track 3336, and can include two drums on each side ofthe RPC track, such as drums 3711 and 3712 (FIG. 37) on each side of RPCtrack 3336. In several embodiments, track 3336 can include a track wheel3638 (FIGS. 36-37) at one end of RPC track 3336 and a track wheel 3739(FIG. 37) at the other end of RPC track 3336. In some embodiments, trackwheel 3638 can be of a one side of RPC track 3336, such as on the sameside as drum 3711, and track wheel 3739 can be on the other side of RPCtrack 3336, such as drum 3712.

As shown in FIG. 37, in several embodiments, a cable 3713 (FIG. 37, notshown in other FIGS. for clarity) can be wrapped around drum 3711,extend from the front side of drum 3711 under drum 3711 and be woundaround track wheel 3638, extend under RPC track 3336 to track wheel3739, and be wound around track wheel 3739 to extend under and arounddrum 3712. In many embodiments, cable 3712 can be attached to RPC 3260under RPC track 3336, such as on carrier frame 3510 (attachment notshown). In many embodiments, cable 3713 can create a positive engagementsystem, such that when RPC drive shaft 3233 rotates in a firstrotational direction and rotates drums 3711-3712 in the first rotationaldirection, drum 3711 can further wind cable 3713 while drum 3712 unwindscable 3713, which can result in cable 3713 moving RPC 3260 in a rearwarddirection. Similarly, when RPC drive shaft 3233 rotates in a seconddirection and rotates drums 3711-3712 in the second rotationaldirection, drum 3712 can further wind cable 3713 while drum 3711 unwindscable 3713, which can result in cable 3713 moving RPC 3260 in afrontward direction. As shown in FIG. 36, RPC motor 3231 can use RPCdrive block to drive RPC drive shaft 3230 in either rotationaldirection.

In many embodiments, each RPC (e.g., 3240, 3250, 3260, 3270 (FIGS.32-34)) on harvesting vehicle 3200 can be driven by RPC drive shaft3233, which is in common, and which can move and position each RPC(e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34)) together to the sameposition above the different plant beds (e.g., 3284-3287 (FIGS. 32-34)).

Turning ahead in the drawings, FIG. 38 illustrates a set of time views3811-3817 over time showing side views of a progression of an RPC 3803on a track 3802 over a plant bed 3801. FIG. 39 illustrates a schematicof a portion of plant bed 3801, showing the position of robots carriedby RPC 3803 over time. RPC 3803 can be similar or identical to RPCs3240, 3250, 3260, or 3270 (FIGS. 32-34). Track 3802 can be similar oridentical to RPC tracks 3334-3337 (FIGS. 33-34). In many embodiments,RPC 3802 can carry robots 3804-3807, which can each by similar oridentical to harvesting robot 100 (FIG. 1) or harvesting robot 2000(FIG. 1), or another suitable robot. For example, robots 3804-3807 canbe hole punching robots. Time views 3811-3817 can proceed sequentially,showing the progression of RPC 3803 and track 3802 over plant bed 3801.

Plant bed can include a plant row 3901 (FIG. 39) and a plant row 3902(FIG. 39), which can each be a straight or curved row of plants. Forexample, plant row 3901 can include plants 3881-3895 and plant row 3902can include plants 3821-3835. In some embodiments, robots 3804-3807 canpick plants 3881-3895 and 3821-3835, based on the pattern legend shownin FIG. 39, and as described below in further detail.

In many embodiments, track 3802 be attached to a vehicle, such asharvesting vehicle 3200 (FIGS. 32-34), or another suitable vehicle. Inmany embodiments, the vehicle can proceed at an approximately constantvelocity, such that track 3802 proceeds at an approximately constantvelocity in a first direction (e.g., right to left in FIG. 38) withrespect to plant bed 3801. In many embodiments, RPC 3803 can move withrespect to track 3802, such as explained above for RPC 3260 and RPCtrack 3336 in connection with FIGS. 36-37. In many embodiments, themovement of RPC 3803 with respect to track 3802 can beneficially keeprobots 3804-3807 in a stationary position with respect to plant bed3801.

As shown in FIG. 38, time views 3811 and 3812 are progressive time viewsduring a first time period in which RPC 3803 is held in a first carrierposition and stationary with respect to plant bed 3801 while track 3802moves in the first direction with respect to plant bed 3801. While inthe first carrier position, the robots (e.g., 3804-3807) can be carriedin a stationary manner at a first set of robot positions, such thatrobot 3807 is carried in a stationary manner at plant 3821, robot 3806is carried in a stationary manner at plant 3881, robot 3805 is carriedin a stationary manner at plant 3824, and robot 3804 is carried in astationary manner at plant 3884. As shown in time views 3811 and 3812,RPC 3803 is held in the first carrier position and the first set ofrobot positions remains constant as track 3802 proceeds in the firstdirection. To achieve this station-keeping of RPC 3803, RPC 3803 canmove with respect to track 3802 in a second direction that is oppositethe first direction at the same velocity that track 3802 moves in thefirst direction with respect to plant bed 3801.

At a time period extending between the time views shown in time views3812-3813, RPC 3802 can move from the first carrier position to a secondcarrier position. The movement of RPC 3802 from the first carrierposition to the second carrier position can be an adjacent progression.Adjacent progression can refer to the robots moving to a positionimmediately next to the previous position, such as moving to the nextplant in a row of plants. To achieve this adjacent progression of RPC3803, RPC 3803 can move with respect to track 3802 in the firstdirection while track 3802 continues to move in the first directionrespect to plant bed 3801, such that RPC 3803 moves fasted in the firstdirection with respect to plant bed 3801 than track 3802 moves in thefirst direction with respect to plant bed 3801.

Time views 3813 and 3814 are progressive time views during a second timeperiod in which RPC 3803 is held in the second carrier position andstationary with respect to plant bed 3801 while track 3802 moves in thefirst direction with respect to plant bed 3801. While in the secondcarrier position, the robots (e.g., 3804-3807) can be carried in astationary manner at a second set of robot positions, such that robot3807 is carried in a stationary manner at plant 3822, robot 3806 iscarried in a stationary manner at plant 3882, robot 3805 is carried in astationary manner at plant 3825, and robot 3804 is carried in astationary manner at plant 3885. As shown in time views 3813 and 3814,RPC 3803 is held in the second carrier position and the second set ofrobot positions remains constant as track 3802 proceeds in the firstdirection. To achieve this station-keeping of RPC 3803, RPC 3803 canmove with respect to track 3802 in a second direction that is oppositethe first direction at the same velocity that track 3802 moves in thefirst direction with respect to plant bed 3801.

At a time period extending between the time views shown in time views3814-3815, RPC 3802 can move from the second carrier position to afourth carrier position. The movement of RPC 3802 from the secondcarrier position to the fourth carrier position can be an adjacentprogression. To achieve this adjacent progression of RPC 3803, RPC 3803can move with respect to track 3802 in the first direction while track3802 continues to move in the first direction respect to plant bed 3801,such that RPC 3803 moves fasted in the first direction with respect toplant bed 3801 than track 3802 moves in the first direction with respectto plant bed 3801.

Time views 3815 and 3816 are progressive time views during a fourth timeperiod in which RPC 3803 is held in the fourth carrier position andstationary with respect to plant bed 3801 while track 3802 moves in thefirst direction with respect to plant bed 3801. While in the fourthcarrier position, the robots (e.g., 3804-3807) can be carried in astationary manner at a fourth set of robot positions, such that robot3807 is carried in a stationary manner at plant 3823, robot 3806 iscarried in a stationary manner at plant 3883, robot 3805 is carried in astationary manner at plant 3826, and robot 3804 is carried in astationary manner at plant 3886. As shown in time views 3815 and 3816,RPC 3803 is held in the fourth carrier position and the fourth set ofrobot positions remains constant as track 3802 proceeds in the firstdirection. To achieve this station-keeping of RPC 3803, RPC 3803 canmove with respect to track 3802 in a second direction that is oppositethe first direction at the same velocity that track 3802 moves in thefirst direction with respect to plant bed 3801.

At a time period extending between the time views shown in time views3816-3817, RPC 3802 can move from the fourth carrier position to a thirdcarrier position. The movement of RPC 3802 from the fourth carrierposition to the third carrier position can be a leap-frog progression.Leap-frog progression can refer to the robots moving to a position thatis not immediately next to the previous position and which skips (or“leap over”) other positions that have already been serviced, such asmoving from a plant in a row of plants to another plant in a row ofplants that is beyond other plants that have already been picked. Toachieve this leap-frog progression of RPC 3803, RPC 3803 can move withrespect to track 3802 in the first direction while track 3802 continuesto move in the first direction respect to plant bed 3801, such that RPC3803 moves fasted in the first direction with respect to plant bed 3801than track 3802 moves in the first direction with respect to plant bed3801. In many embodiments, RPC 3803 can move faster in the firstdirection with respect to track 3802 during the leap-frog progressionthan during the adjacent progression.

Time view 3817 is a time view during a third time period in which RPC3803 is held in the third carrier position and stationary with respectto plant bed 3801 while track 3802 moves in the first direction withrespect to plant bed 3801. While in the third carrier position, therobots (e.g., 3804-3807) can be carried in a stationary manner at athird set of robot positions, such that robot 3807 is carried in astationary manner at plant 3827, robot 3806 is carried in a stationarymanner at plant 3887, robot 3805 is carried in a stationary manner atplant 3830, and robot 3804 is carried in a stationary manner at plant3890. RPC 3803 is held in the third carrier position and the third setof robot positions remains constant as track 3802 proceeds in the firstdirection. To achieve this station-keeping of RPC 3803, RPC 3803 canmove with respect to track 3802 in a second direction that is oppositethe first direction at the same velocity that track 3802 moves in thefirst direction with respect to plant bed 3801. In many embodiments, theprocess can repeat similarly as explained in the progression of timeviews 3811-3817 in the progressed robot positions to continuepositioning the robots at progressed plant positions for plants 3828,3829, 3831-3835, and so forth for plant row 3902, for plants 3888, 3889,3891-3895, and so forth for plant row 3901.

At each set of robot positions, the robots (e.g., 3804-3807) can performtasks simultaneously. For example, if robots 3804-3807 are harvestingrobots (e.g., harvesting robot 100 (FIG. 1), harvesting robot 2000 (FIG.20)), robots 3804-3807 can each independently and simultaneously rotatearound the plants at the set of robot positions to detect and pick cropsfrom the plants. In many embodiments, the times at which the robots(e.g., 3804-3807) are kept at each of the set of robot positions candepend on the nature of the task. For example, for picking crops usingharvesting robots, RPC 3803 can remain at each set of robot positionsfor a set time, such as 8 seconds, or another suitable time required forpicking crops. For another type of robots, such as hole-punching robots,the time at each position can be shorter, such as 1 second, or anothersuitable time period. In many embodiments, the movement from a set ofrobot positions to the next set of robot positions for an adjacentprogression can be a suitable time required to move RPC 3803 to the nextset of robots positions. For example, for picking crops using harvestingrobots, RPC 3803 can perform the adjacent progression during a set time,such as 1.5 seconds, or another suitable time required for moving RPC3803 in the adjacent progression. In many embodiments, the movement froma set of robot positions to the next set of robot positions for aleap-frog progression can be a suitable time required to move RPC 3803to the next set of robots positions when leap-frogging other sets ofrobot positions. For example, for picking crops using harvesting robots,RPC 3803 can perform the leap-frog progression during a set time, suchas 2.5 seconds, or another suitable time required for picking crops, oranother suitable time required for moving RPC 3803 in the leap-frogprogression.

In many embodiments, the station-keeping of RPC 3803 in each set ofrobot positions can advantageously allow the vehicle (e.g., harvestingvehicle 3200 (FIGS. 32-34) to move at an approximately constantvelocity, such that the vehicle does not need to start and stop betweeneach set of robot positions, and such that the vehicle can avoid wastedtime required to start and stop and the large amount of wasted energynecessary to accelerate and decelerate the vehicle at each start andstop.

Turning ahead in the drawings, FIG. 40 illustrates a top view of rows ofplant beds 4000 showing a vehicle 4001 in a progression of time views4011-4013 as vehicle 4001 moves through rows of plant beds 4000. Vehicle4001 is merely exemplary, and embodiments of the vehicle are not limitedto embodiments presented herein. The vehicle can be employed in manydifferent embodiments or examples not specifically depicted or describedherein. Vehicle 4001 can be similar or identical to vehicle 3200 (FIGS.32-34), and can show only portions of vehicle 3200 for clarity. Forexample, vehicle 4001 can include a body with four RPC tracks 4004-4007,which can be similar or identical to RPC tracks 3334-3337 (FIGS. 33-34),and can carry RPCs, such as RPCs 3240, 3250, 3260, and 3270 (FIGS.32-34), respectively, but not shown here in FIG. 40. In manyembodiments, vehicle 4001 can include wheels at each side of vehicle4001, such as wheels 4002 at a first side of vehicle 4001 and wheels4003 at a second side of vehicle 4001.

In many embodiments, vehicle 4001 can move through rows of plant beds4000, which can include plant beds, such as plant beds 4021-4032, androws, such as rows 4041-4051, between the plant beds (e.g., 4021-4032).In several embodiments, wheels 4002-4003 can roll along rows (e.g.,4041-4051) between the plant beds (e.g., 4021-4032). For example, insome embodiments, as shown in time view 4011, wheels 4002 can roll alongrow 4047 and wheels 4003 can roll along row 4041, such that vehicle 4001straddles six plant beds (e.g., plant beds 4021-4027), and can be usedto harvest and/or punch holes in four plant beds (e.g., plant beds4023-4026) at a time. For example, track 4004 can be positioned overplant bed 4026, track 4005 can be positioned over plant bed 4025, track4006 can be positioned over plant bed 4024, and track 4007 can bepositioned over plant bed 4023. In other embodiments, vehicle 4001 canstraddle more or fewer plant beds and can harvest more or fewer plantbeds at a time. Vehicle 4001 can progress along the rows (e.g., 4041,4047) in a first direction to harvest and/or punch holes on the plantbeds (e.g., 4023-4026), such as right to left in FIG. 40. The rows canbe straight or curved.

As shown in time view 4012, after reaching the end of the rows (e.g.,4023-4026), vehicle 4001 can turn wheels 4002 and 4003 at a right angleto proceed to a next set of rows. After reaching the next set of rows,vehicle 4001 can again turn wheels 4002 and 4003 at a right angle toproceed along the next set of rows in a second direction that isopposite the first direction, such as left to right in FIG. 40. In manyembodiments, each wheel (e.g., 4002, 4003) can turn independently.

As shown in time view 4013, wheels 4002 can roll along row 4045 andwheels 4003 can roll along row 4051, such that vehicle 4001 straddlessix plant beds (e.g., plant beds 4026-4031), and can be used to harvestand/or punch holes in four plant beds (e.g., plant beds 4027-4030) at atime. For example, track 4004 can be positioned over plant bed 4030,track 4005 can be positioned over plant bed 4029, track 4006 can bepositioned over plant bed 4028, and track 4007 can be positioned overplant bed 4027. Vehicle 4001 can similarly progress along rows of plantbeds 4000 in a serpentine fashion to process each row of plant beds4000. In many embodiments, vehicle 4001 can be guided by a guidancecontrol system, as explained below in greater detail.

In many embodiments, vehicle 4001 can be used to punch holes forplanting plants for crops (e.g., strawberries or other crops) carryharvesting robots (e.g., 100 (FIG. 1), 2000 (FIGS. 20-21)) for pickingcrops (e.g., strawberries or other crops). In many embodiments, aguidance control system can position RPCs (e.g., 3240, 3250, 3260, 3270(FIGS. 32-34)), which can carry hole-punching robots to punch holes, asshown in FIG. 43 and described below, to carry harvesting robots (e.g.,100 (FIG. 1), 2000 (FIGS. 20-21)), or other suitable robots. In manyembodiments, the robots can be positioned to perform tasks (e.g., holepunching, picking crops, etc.) by the guidance control system based on alocation from GPS receivers (e.g., GPS receivers 3215-3216 (FIGS.32-34)) and/or other approaches, such as those described below.

For many types of plants, there are three phases in a lifecycle of theplants in the field, namely planting, growing, and harvesting. At theoutset, there are no plants in the field, and as such the placement andpositioning of the plants is not established. In some embodiments, theguidance control system can calculate target plant locations based on aninitial reference position and a heading. These target plant locationscan then be used to position the RPCs (e.g., 3240, 3250, 3260, 3270(FIGS. 32-34)) and robots carried by the RPCs to punch the holes for theactual plants. In a number of embodiments, the actual plant locationscan be stored in a database for later use. In some embodiments, theplant locations can be stored based on a reference position and aheading, with offsets calculated based on fixed spacing between plants.

Knowing the plant locations accurately can be an important aspect infacilitating the positioning of vehicle 4001 over the center of theplants in a repeatable manner. However, the nature of commercial,stand-alone GPS generally contains error sources that combine toinfluence the position error of the GPS solution over time. StandardPositioning Service (SPS) GPS positioning can contain horizontal errorson the order of 10 meters. Wide-area augmentation types, such as WAAS(Wide Area Augmentation System) in the United States, can reduce thaterror to meter-level, with additional augmentation services andtechniques reducing the error even further, down to decimeter-level forlocal-area differential GPS (LADGPS), and centimeter-level accuracy forReal-Time Kinematic (RTK) systems.

Accurate positioning of vehicle 4001 facilitates accurate determinationof the RPCs (e.g., 3240, 3250, 3260, 3270 (FIGS. 32-34)) and robotscarried by the RPCs, which, when combined with knowledge of the multiplerobot positions on the RPC and/or plant locations, can be used toperform tasks with multiple robots at the same time (e.g., pickingmultiple plants at the same time).

A potential challenge when trying to hold sub-inch accuracy with GPSalone is that commercially available GPS systems are generally onlyaccurate down to 0.433 inches (1.10 cm) when using RTK, and may have aslow refresh rate. While moving at approximately 1 mile per hour (mph)(1.61 kilometers per hour (kph)), with a 20 Hertz (Hz) position outputfrom the GPS, vehicle 4001 can move 0.12 inch (0.30 cm) every second,and 0.0061 inch (0.0154 cm) between each GPS position refresh. Slowerrefresh rates, or a faster harvester speed, can result in a greaterdistance traveled between each GPS position refresh. Some embodimentsmay work around a slower refresh rate by using a combination of GPS anddead reckoning using a velocity of vehicle 4001 to estimate the currentposition of the harvester.

When rows (e.g., rows 4041-4051) are on 50 inch (127 cm) centers, withthe distance between plants being even smaller, such distances can leadto inaccuracies due to floating point rounding during the computationprocess utilizing a purely latitude and longitude-based referencesystem. Computing geographical distance using the law of cosines cancause such errors over small distances, as the cosine value approaches1.0. Alternatives, such as the Haversine formula, can suffer from errorderived from treatment of the Earth as a sphere, rather than an oblatespheroid. Vincenty's solutions can offer advantages suited to the needsof plant location calculations. Vincenty's solutions are derived as twoiterative methods: (a) a direct solution, which computes a second pointgiven an initial position, a bearing (heading), and a distance; and (b)an inverse solution, which computes the distance and bearing between twopoints

The start location of a row can be given by either an area around astart point or by a start line defined by two points. A distance canthen be calculated from the start location for each of the plants in therow. The distance traveled can then be calculated as the tractor movesdown the row by using a number of different inputs such as GPS-basedvelocity, ground-based velocity, the time from last GPS update, last GPSlocation, and/or direction of travel. With this, a more accurateestimate of the distance travelled can be calculated than with justusing GPS locations alone.

In the eyes of advance planning, some embodiments may traverse the rowwith vehicle 4001 to get the start and stop coordinates for each rowalong with the travel direction (heading) of the row. From there, thestart locations of each row can be calculated from the start location ofthe first row in the set.

When calculating the plant locations using a latitude/longitude system,the use of Vincenty's direct solution allows for calculation of aposition given an initial position, a bearing, and a distance. This canform a two-part solution to find the origin of each row, given the fieldstarting point and the direction the rows are to run, and the distancebetween each row, and the location of each plant in the row, given thedirection the rows are to run and the distance between each plant.

For the first step of the process, the equation below gives the originposition for each row:

$\left( {\phi_{{row},i},\lambda_{{row},i}} \right) = {v\left( {\phi_{0},\lambda_{0},{\psi_{field} \pm \frac{\pi}{2}},{\delta\;{row}}} \right)}$where φ_(row,i) and λ_(row,i) are the latitude and longitude,respectively, of the start of the row, φ₀ and λ₀ are the latitude andlongitude, respectively, of the field origin point, ψ_(field) is theheading of the field's rows, δrow is the distance between rows, and thefunction V(x) is Vincenty's direct solution.

Once the origin position for each row is known, the position of eachplant in the row can be calculated:(φ_(plt,n),λ_(plt,n))=V(φ_(row,i),λ_(row,i),ψ_(field) ,δplt)where φ_(plt,n) and λ_(plt,n) are the latitude and longitude,respectively, of the n^(th) plant in the row, φ_(row,i) and λ_(row,i)are the latitude and longitude, respectively, of the start of the row,ψ_(field) is the heading of the field's rows, δplt is the distancebetween plants in the row, and the function V(x) is Vincenty's directsolution.

In order to accurately place the robots over each plant, the location ofthe GPS with respect to each row as well as the location of the RPC(Robot Position Carrier) with respect to the phase center of the GPSantenna can be determined. Accurately knowing all these values in orderto hold +/−0.75 inch (1.90 cm) tolerance on the robots can presentchallenges. As discussed above, the accuracy of GPS is at best 0.433inch (1.10 cm), which uses up most of the tolerance. Another possibleissue is that a slow refresh rate for GPS position output can causeuncertainty with the current position and velocity of vehicle 4001 ifthe drive system of vehicle 4001 causes unanticipated acceleration ordeceleration to occur between updates.

Turning ahead in the drawings, FIG. 41 illustrates a top view of avehicle 4001, showing an X-axis and a Y-axis in a coordinate system fora guidance control system. FIG. 42 illustrates a rear view of a vehicle4001, showing a Y-axis and a Z-axis in the coordinate system of FIG. 41for a guidance control system. When discussing items such as platformattitude and lever arms, the guidance control system can use a definedreference frame from which to derive measurements and to assign axes ofrotation for the platform attitude parameters. Viewing movement andtranslations from the perspective of a theoretical driver on vehicle4001 can be defined by a “body frame” of vehicle 4001, denoted by B witha subscript for each axis (e.g., B_(x), B_(y), B_(y)). The body frame Bcan be defined as a right-hand coordinate system, with the positiveX-axis pointing in the direction shown in FIG. 41, which can be in thesame direction of tracks 4004-4007, and the positive Y-axis pointing ina direction from wheels 4003 to wheels 4002, as shown in FIG. 41. As thecoordinate system is right-handed, the positive Z axis can pointdownward from the bottom of the platform towards the ground, as shown inFIG. 42.

The direction of travel can change if the harvester platform is drivenalong a row in the opposite direction, but the body frame axes describedhere will not change with the direction of travel. With the body frameaxes defined, as shown in FIGS. 41-42, attitude parameters,specifically, roll, pitch, and yaw, can be defined. Roll is a rotationabout the body-X axis, tilting the platform from side to side. Pitch isa rotation about the body-Y axis, and is equivalent to tilting theplatform forward or backward. Yaw is about the body-Z axis, and is thedirection the platform is facing.

Each GPS receiver (e.g. 3215-3216 (FIGS. 32-34)) can provide thecalculated position of the phase center of the antenna of the GPSreceiver (e.g. 3215-3216 (FIGS. 32-34)). This calculated position can beused to navigate vehicle 4001, although the physical mounting locationof the GPS receiver (e.g. 3215-3216 (FIGS. 32-34)) on the frame pieces(e.g., 3211-3212 (FIGS. 32-34)) are is usually not ideal for thispurpose because of clear-sight line blockages. In many embodiments, GPSreceivers (e.g., 3215-3216 (FIGS. 32-35)) can be mounted on the top ofvehicle 4001, such as on arms 3213-3214 (FIGS. 32-34), respectively, asshown on harvesting vehicle 3200 (FIGS. 32-34) to allow for clear sightlines, which can facilitate improved GPS reception

In order to provide a position that is conducive for autonomousnavigation, the GPS position can be referenced to a guidance controlpoint (GCP) 4100. GCP 4100 can serve as a reference for calculatingother locations on vehicle 4001, such as positions of each RPC (e.g.,3240, 3250, 3260, 3270 (FIGS. 32-34)) and each robot (e.g., 3461-3464(FIG. 34)) carried by each RPC (e.g., 3240, 3250, 3260, 3270 (FIGS.32-34)). The GCP can be used as the reference point when navigatingvehicle 4001. Calculating the position of GCP 4100 from the GPS positioncan involve incorporating lever arm information for each of the GPSreceivers (e.g., 3215-3216 (FIGS. 32-34)) on arms 3213-3214 (FIGS.32-34) with respect to GCP 4100.

The lever arm information for the GPS receivers (e.g., 3215-3216 (FIGS.32-34)) can be determined through measurement, either on vehicle 4001itself or through the use of a modeling program to determine thedistances. In most embodiments, the guidance control system canincorporation additional lever arm information for each of the robots.This lever arm information for the robots, when used in conjunction withthe lever arm information for the GPS receivers (e.g., 3215-3216 (FIGS.32-34)) can allow for the position of each robot to be calculated basedon the position of the GPS receivers (3215-3216 (FIGS. 32-34)). If theassumptions can be made that the RPC (e.g., 3240, 3250, 3260, 3270(FIGS. 32-34)) is aligned with the body-forward (X) axis, the absoluteposition of each robot, u, can be determined.

The attitude, namely heading, pitch, and roll, of vehicle 4001 can beused to form a Direction Cosine Matrix (DCM) relating the attitude ofvehicle 4001 to the north-pointing navigation frame. This DCM, calledC_(B) ^(N), is shown below:

$C_{B}^{N} = \begin{bmatrix}{\cos\;\theta\;\cos\;\psi} & {{{- \cos}\;\phi\;\sin\;\psi} + {\sin\;\phi\;\sin\;\theta\;\cos\;\psi}} & {{\sin\;\phi\;\sin\;\psi} + {\cos\;{\phi sin}\;\theta\;\cos\;\psi}} \\{\cos\;\theta\;\sin\;\psi} & {{\cos\;\phi\;\cos\;\psi} + {\sin\;\phi\;\sin\;\theta\;\sin\;\psi}} & {{{- \sin}\;\phi\;\cos\;\psi} + {\cos\;{\phi sin}\;\theta\;\sin\;\psi}} \\{{- \sin}\;\theta} & {\sin\;{\phi cos}\;\theta} & {\cos\;{\phi cos}\;\theta}\end{bmatrix}$where ψ is the heading of the vehicle 4001, θ is the pitch, and φ is theroll.

Attitude measurement with only two GPS antennas can suffers from a lackof adequate degrees of freedom to truly measure all 3 axes of rotation.Since any rotation about the axis formed between the two receivers isinvisible without external aiding, only two components of platformattitude (i.e., (a) heading and (b) either pitch or roll) can bemeasured.

In order to alleviate the missing degree of freedom, assumptions can bemade about the platform, such that it is approximately level at alltimes, or that the platform's roll (as it exists across the longestdimension of the harvester platform) is negligible. However, thisapproach eliminates any possibility of GPS-only measurement of themissing axis to aid in leveling of the harvester platform itself, anddoes not allow for measurement of potentially sloped areas (e.g.,California fields).

Error in determination of the horizontal position of the RPC (e.g.,3240, 3250, 3260, 3270 (FIGS. 32-34)) is dominated by heading error,rather than pitch or roll. Some embodiments may use two GPS receivers,or a dual-antenna GPS receiver, to calculate the platform heading. Usingthe accuracy of RTK GPS coupled with a separation of several metersbetween antennas (or receivers) can reduce the heading error to lessthan a few tenths of a degree.

In order to provide visibility to the remaining aspects of the attitudeof vehicle 4001, namely pitch and roll, a low-cost Inertial MeasurementUnit (IMU) consisting of a triad of orthogonal accelerometers (“accels”)and gyroscopes (“gyros”) to measure the inertial accelerations ofvehicle 4001, allowing for a pitch and roll attitude solution to becalculated without the use of GPS data. In many embodiments, vehicle4001 can include an IMU, such as in a GPS receiver (e.g., 3215 or 3216(FIGS. 32-34)) or at another position.

By itself, an inertial measurement system using low-cost sensors can benot sensitive enough to determine the platform heading, as it can merelydetermine the offset from the initial starting point as measured by thegyros. Use of a multiple GPS (or a multi-antenna GPS) system can allowfor an absolute heading reference, which can be aided by gyromeasurements to account for a loss of GPS, if desired. The low dynamicenvironment of vehicle 4001 and the clear-sky nature of a farm combineto make this a low probability occurrence.

In order to compute the lever arm calculations using geodeticcoordinates, some intermediary calculations can be performed by theguidance control system. These calculations can be made with the sameassumptions described above. The body frame to navigation frame matrixcan be applied to the lever arm information for the RPCs (e.g., 3240,3250, 3260, 3270 (FIGS. 32-34)) (e.g. lever arm for RPC in the X axis(LA_(RPC,X)), lever arm for RPC in the Y axis (LA_(RPC,Y)), and leverarm for RPC in the Z axis (LA_(RPC,Z)), with the body-X axis adjustedbased on the distance (δPos_(RPC)) of the RPC (e.g., 3240, 3250, 3260,3270 (FIGS. 32-34)) from home, to form the lever arm distance offsets interms of the north, east, and downward (as with body frame, positivebeing downward) (NED) axes.

${L\; A_{{R\; P\; C},{N\; E\; D}}} = {C_{B}^{N}\begin{bmatrix}{{L\; A_{{R\; P\; C},X}} + {\delta\;{Pos}_{R\; P\; C}}} \\{L\; A_{{R\; P\; C},Y}} \\{L\; A_{{R\; P\; C},Z}}\end{bmatrix}}$The equations for application of a lever arm to a position can bederived from equations used to calculate a change in position due to avelocity. If the assumption is made that the lever arm distances isactually a velocity over a 1 second period, the change in positionformulas can be used to compute the change in latitude (δφ) andlongitude (δλ).

${\delta\;\phi} = \frac{v_{N}}{R_{M} + h}$${\delta\;\lambda} = \frac{v_{E}\sec\;\phi}{R_{T} + h}$where φ is the current latitude, h is the current elevation, ν_(N) isthe velocity in the north direction, and ν_(E) is the velocity in theeast direction. R_(M) is the meridional radius of curvature, and R_(T)is the transverse radius of curvature of the Earth, such that:

$R_{M} = \frac{R_{P}\left( {1 - e^{2}} \right)}{\sqrt{1 - {e^{2}\sin^{2}\phi}}}$$R_{T} = \frac{R_{P}}{\sqrt{1 - {e^{2}\sin^{2}\phi}}}$where R_(P) is the polar radius, R_(P)=6378137.0m, and e² is theeccentricity of the ellipsoid, e²≅0.00669438.

Once the position change due to the lever arm has been calculated, theposition change can be applied to the GPS position:φ_(RPC)=φ_(GPS)+δφλ_(RPC)=λ_(GPS)+δλwhere φ_(RPU) is the latitude of the RPC, λ_(RPU) is the longitude ofthe RPC, φ_(GPS) is the latitude of the GPS, and λ_(GPS) is thelongitude of the GPS.

Due to the length of the berry picking season, there is a source ofpositional error that slowly grows over time due to the movement of thecontinental plates. The plates themselves move anywhere from 1 to 10 cmper year, eating into the positioning error budget. Using standard GPS,this measurement error can be lost in the noise and uncertainty presentin the system, but with RTK GPS, this error will show up as a positionbias at a later time if no compensation is used. In order to compensatefor this, the base station position can be surveyed before planting, andthen surveyed again before harvesting is to be performed. Someembodiments may apply the position difference as an offset to the storedplant locations.

In many embodiments, the guidance control system advantageously canprovide positioning accuracy for each robot within 0.5 inch (1.27 cm).In some embodiments, the positioning accuracy for each robot using theguidance control system can be more precise, such as within 0.25 in(0.635 cm), which has been measured in testing of the guidance controlsystem. In many embodiments, the guidance control system can facilitateprecision agriculture, such that each individual plant location (e.g.,for plant, growing, and/or harvesting) is tracked. In severalembodiments, precision agriculture provided by the guidance controlsystem can allow picked crops to be traced to the individual plant orlimited group of individual plants from which the crops were picked. Forexample, a package of strawberries can include an identifier that can beused to trace the strawberries picked to a group of plants (e.g., 8plants, or another suitable number of plants) at tracked locations.

Turning ahead in the drawings, FIG. 43 illustrates a top view of a plantbed 4300, showing holes punched for growing plants. As explained above,in many embodiments, the robots of vehicle 4001 (FIG. 40) or harvestingvehicle 3200 (FIGS. 32-34) can include hole punching robots (e.g., inharvesting vehicle 3200 (FIGS. 32-34), the harvesting robots (e.g.,3461-3464 (FIGS. 34-35) can be replaced with hole punching robots). Forexample, each hole punching robot can be a pneumatic actuator of acylindrical shaft which can punch a hole in a plant bed, such as throughplastic on a plant bed, to create a hole in order to plant a plant(e.g., a strawberry plant or other type of plant). In many embodiments,the vehicle (e.g., vehicle 4001 (FIG. 40) or harvesting vehicle 3200(FIGS. 32-34)) can carry the hole punch robots on the RPCs (e.g., 3240,3250, 3260, 3270 (FIGS. 32-24)) to punch rows of holes, such as rows ofholes 4321 and 4322. For example, row of holes 4321 can include holes4301, 4302, and 4303 in a row, and ow of holes 4322 can include holes4311, 4312, and 4313 in a row. In many embodiments, each of the holes ina row can be approximately equally spaced. As indicated previously, therow can be straight or curved.

Turning ahead in the drawings, FIG. 44 illustrates a side view ofsuspension components 4400 for adjusting a vertical position of a wheel4401 with respect to a body 4406. Suspension components 4400 are merelyexemplary, and embodiments of the suspension components are not limitedto embodiments presented herein. The suspension components can beemployed in many different embodiments or examples not specificallydepicted or described herein. In a number of embodiments, suspensioncomponents 4400 can include wheel 4401, an axle 4402, a wheel stanchion4403, a turning assembly 4404, a wheel mount 4405, body 4406, adjustmentmechanism 4407, and/or actuator 4408. Wheel 4401 can be similar oridentical to wheels 3201-3204 (FIGS. 32-34) and/or 4002-4003 (FIGS.40-43). Body 4406 can be a portion of body 3210 (FIGS. 32-34), such as aportion of arms 3213-3214 (FIGS. 32-24).

In many embodiments, wheel 4401 can be coupled to and rotate around axle4402, which can be coupled to wheel stanchion 4403. In variousembodiments, wheel stanchion 4403 can be movably coupled to wheel mount4405 by turning assembly 4404, which can allow wheel 4401 to be turnedin a different direction. In several embodiments, wheel mount 4405 canbe movably coupled to body 4406 by adjustment mechanism 4407, which canbe a slidably coupling or another suitable coupling, which can allowwheel mount 4405 to adjust vertically with respect to body 4406. Inseveral embodiments, wheel mount 4405 can be adjusted vertically up ordown with respect to body 4406 with actuator 4408. Actuator 4408 can bea hydraulic or electric actuator, for example. In several embodiments,actuator 4408 can be controlled by a suspension control system, such assuspension control system 5803 (FIG. 58, described below), which in someembodiments can be an active suspension system.

In various embodiments, the suspension control system (e.g., 5803 (FIG.58, described below)) can control the vertical position of wheel 4401with respect to body 4406. When wheel 4001 is on a surface, adjustingthe vertical position of wheel 4001 with respect to body 4406 can raiseor lower body 4406 with respect to the surface. In many embodiments, theassembly for each wheel on the vehicle (e.g., wheels 3201-3204 (FIGS.32-34) on harvesting vehicle 3200 (FIG. 32) and/or 4002-4003 (FIGS.40-43) on vehicle 4001 (FIG. 40)) can include suspension components4400.

Forexample, in some embodiments, the range of vertical adjustment of wheel4401 with respect to body 4406 can be 10 inches (25.4 cm). In otherembodiments, the range of vertical adjustment can be more or less than10 inches (25.4 cm).

Turning ahead in the drawings, FIG. 45 illustrates a perspective view ofa vehicle 4500, showing a body 4520 of vehicle 4500 in a loweredsuspension position. FIG. 46 illustrates a perspective view of vehicle4500, showing a body 4520 of vehicle 4500 in a raised suspensionposition. Vehicle 4500 is merely exemplary, and embodiments of thevehicle are not limited to embodiments presented herein. The vehicle canbe employed in many different embodiments or examples not specificallydepicted or described herein. Vehicle 4500 can be similar or identicalto vehicle 4001 (FIG. 40) and/or harvesting vehicle 3200 (FIGS. 32-34),and various components of vehicle 4500 can be similar or identical tovehicle 4001 (FIG. 40) and/or harvesting vehicle 3200 (FIGS. 32-34).

In many embodiments, vehicle 4500 can include a body 4520 and wheels4501-4504, which can each be part of associated suspension components4511-4514, respectively. Suspension components 4511-4514 each can besimilar or identical to suspension components 4400 (FIG. 44), and canraise and/or lower the vertical position of wheels 4501-4504,respectively, with respect to body 4520.

In many embodiments, suspension components 4511-4514 for each wheel4501-4504 can operate independently from the other suspension components(e.g., 4511-4514). In many embodiments, one or more of suspensioncomponents 4511-4514 can allow one or more of wheels 4501-4504 to bevertically adjusted with respect to the body while not adjusting otherwheels (e.g., 4501-4504). In some embodiments, suspension components4511-4514 can adjust wheels 4501-4504 at different vertical adjustmentamounts. For example, as shown in FIG. 45 vehicle 4500 can be positionedlower than vehicle 4500 in FIG. 46.

In many embodiments, vehicle 4500 can carry one or more robots, such asharvesting robots 3461-3464 (FIGS. 34-35) in harvesting vehicle 3200(FIGS. 32-34). In many embodiments, each robots can determine a heightof the robot from the plant bed (e.g., plant beds 3281-3290 (FIGS.32-34)), such as by using imaging sensors (e.g., imaging sensors1290-1291 (FIGS. 12-13) and/or images sensors 2190-2191 (FIG. 21)) onthe robots. For example, the imaging sensors can determine that a robot(not shown) on vehicle 4500 in FIG. 45 is at a height 4550 from theplant bed. Similarly, the imaging sensors can determine that a robot(not shown) on vehicle 4500 in FIG. 45 is at a height 4650 from theplant bed, such that height 4650 is greater than height 4550 (FIG. 45).In some embodiments, the height information can be determined by therobot based on the imaging sensors determining the distance from theimaging sensors to the crops to be picked. In other embodiments, theheight information can be determined by the robot based on the distancefrom the imaging sensors to the plant bed.

In many embodiments, more than one robot attached to vehicle 4500 canprovide height information to the suspension control system (FIG. 58,described below)). For example, in some embodiments, each robot canprovide height information to the suspension control system (FIG. 58,described below)). In many embodiments, the suspension control system(FIG. 58, described below)) can receive the height information from therobots and determine how to control the adjustment of the verticalposition of one or more of wheels 4501-4504. In a number of embodiments,the adjustment of one or more wheels (e.g., 4501-4504) can be based onthe height information of one or more robots close to the one or morewheels (e.g., 4501-4504). In other embodiments, the adjustment of one ormore wheels (e.g., 4501-4504) can be based on an average of heightinformation from all of the robots. In other embodiments, the adjustmentof each wheel (e.g., 4501-4504) can be the same for each wheel (e.g.,4501-4504) based on the height information received from one or morerobots.

In some embodiments, the height information can be received from therobots regularly, such as on a cycle, and the suspension control system(FIG. 58, described below)) can provide adjustment control for the oneor more wheels (e.g., 4501-4504) regularly based on updated informationreceived each cycle and/or over a period of cycles. For example, theheight information can be sent from the robots to the suspension controlsystem (FIG. 58, described below)) on a 1 Hz cycle, a 2 Hz cycle, a 4 Hzcycle, or another suitable cycle.

In a number of embodiments, vehicle 4500 (FIG. 45) can operate in anopen field subject to weather. The fields can be leveled and setupinitially to relatively tight specifications upon initiation, but due tothis weather exposure, various areas of the field can be subject tosettling or washout due to water and/or wind erosion. To deal with thisissue and keep the robots within preferred inspection distances forpicking speed considerations, vehicle 4500 can be equipped in severalembodiments with the suspension control system (FIG. 58, describedbelow)) to maintain a level of vehicle 4500, row orientation, and/orproper height above the plant beds for the robots.

In many embodiments, the adjustment of the vertical position of one ormore wheels (e.g., 4501-4504), as controlled by the suspension controlsystem (FIG. 58, described below)), can beneficially keep the robotsfrom crashing into the plant beds as they are carried by vehicle 4500,for example. For example, if a wheel (e.g., 4501-4504) of vehicle 4500start to dip into a washed out area, the suspension control system (FIG.58, described below)) can detect the lowering of the height informationfrom one or more of the robots, and can adjust at least the wheel (e.g.,4501-4504) to compensate and level body 4520 and/or keep the robots adistance from the plant beds.

In some embodiments, for example, a bottom most part of each of thepicking system, excluding the gripper in the picking position that isbeing lowered to pick the crop, can be kept at a distance above theplant bed. For example, the distance can be 2.0 inches (5.08 cm) to 5.0inches (12.7 cm). In other embodiments, the distance can be anothersuitable distance. In a number of embodiments, the suspension controlsystem (FIG. 58, described below)) can keep the bottommost part of therobot from the plant bed when the robot is moving with respect from theplant bed and/or when the robot is being held stationary with respect tothe plant bed by the RPC (e.g., 3240, 3250, 3260, 3270 (FIG. 32)).

Strawberry plants can benefit from trimming off the dead, older growththat gets pushed out from the center of the plant as new growth appears.This trimming can prevent diseases caused by the rotting ofolder-organic debris. Typically, the resources available to do thistrimming by hand are not available on farms due to the labor-intensiveprocess. One of the issues with trimming the plants is that, if diseasesare present on one plant, the disease can spread to adjacent plants byusing common trimming utensils.

In some embodiments, a robot, such as harvesting robots 100 (FIG. 1)and/or 2000 (FIG. 20), and/or leaf displacement system 2800 (FIGS.28-31), can include a cauterizing cutting hot wire or mechanical sicklebar that can slice off the outside older growth as the robot circles theplant or the leaf displacement system captures and holds the foliage(e.g., 1512, as shown in FIG. 20). The razor action and heating of thewire moving across the old outer growth can slice off the vines, whichcan trim the plant back to the newer inner growth. The older growth canthen fall away from the plant after being mechanically stimulated by therobot and/or environmental factors, such as wind or rain. The hot wirecan beneficially sterilize the wire so that, if diseases are present onthe trimmed growth, they will not be passed to plants trimmed downstreamof the diseased plant.
